Yea, I know that it is all about the mass, but I am seeing some people asking this question elsewhere and never getting the straight answer of a solid core exterior steel door like it was a few years back. Thought that I better check. I think that there may be a compromise in door type in order to make sure that it looks just like the other doors in the basement, so solid core interior doors might be what I end up with.

I am also trying to figure out what to do about sealing the bottom. Of the door. A lot of people are using a wood or metal threshold, but that isn't going to go over well with my wife.. I could just put the door a little closer to the floor so that it is a little more snug with the future carpet, but the. The door could get to be difficult to open and close which would be bad....

I went to Menards today because they had a bunch of doors on sale plus had an extra 11% rebate that ended today. The extra 11% is on in-stock items only, and the exterior door I wanted was a special order, so for now I picked up a cheaper interior door that was filled and marked "sound proofing" which as we all know can mean little to nothing. It was already almost closing time, so I figured that I could just return it if need be.

Anyway, I am wondering if I should. It just didn't seem *that* much heavier than a regular hollow door, and as we know, mass is important.

If I look a the link above on 'How to Sweeper,' it mentions not using a door with recessed panels. I wonder why because every other door in out house are those 6 panel designs. Hmmm.... I really want to get a good door for the theater for soundproofing, but the more I dig, the more questions I have about what will actually work.

Oh, and I had a couple of helpers for a few hours today. My daughter and her boyfriend wanted to try doing some drywall, so I put them on measuring and cutting duty...

Wow. Buy a regular solid core door on sale for $75, or buy a steel solid core for $150, or buy a steel solid core door with a 7.25" jamb (to account for the 2x6 wall, plus the 3 layers of drywall) and it jumps up to $400+.

I might do with others did and create my own jamb extensions and if I need to add mass, I can add a 3/4" sheet of MDF to the part that is inside the theater and cover it with an acoustical panel or something.

LOL. I loved this picture that my wife took. My daughter laying on the drywall to hold the T-square, her boyfriend using a blade knife to score the drywall... They took about 15 minutes to put the measurements on to the drywall and make the cut... And I am in the background doing about 20 things in the same amount of time.

That said, I was grateful to have the assistance. It was because of them doing what they did that I could get a bunch of other things done at the same time.
